| titleOfInvention | Production of acyloxyacetic acid compound |
| abstract | PURPOSE: To produce an acyloxyacetic acid compound useful as a synthetic intermediate of various agricultural chemicals and pharmaceuticals, especially an intermediate of herbicides, in high efficiency, without using a catalyst, by reacting an α-halogenoacetic acid compound with a carboxylic acid salt in a specific solvent. n CONSTITUTION: The objective compound of formula III is produced by reacting the α-halogenoacetic acid compound of formula I [X is Cl or Br; R 1 and R 2 are H or alkyl; R 3 is OR' or NR"R'''(R' is alkyl; R" and R''' are H, alkyl or aryl)] with a carboxylic acid salt of formula II (R is H or alkyl; M is alkali metal or alkaline earth metal) in a solvent selected from dimethylsulfoxide, N,N-dimethylformamide, N,N-dimethylacetamide, hexamethylphosphoramide, acetonitrile and 1W3C lower alcohol, at 20W120°C. The amount of carboxylic acid salt can be reduced, and the formation of by-product caused by the polymerization of α- halogenoacetic acid can be suppressed. n COPYRIGHT: (C)1985,JPO&Japio |
